Failed to import ActiveX Control

Question

Why do I get an error that says "Failed to import ActiveX Control" when trying to add a HexSight control in VS2010?

Answer

There is a problem with VS2010 and ActiveX controls. Details can be found at http://support.microsoft.com/kb/2066987 (basically, the issue is that the information fails to load in the proper place). To fix this, install the proposed HotFix.

Once installed, make sure you reboot the PC. You will also need to reinstall HexSight for the registration process to be completed.
